Was on the way down the hill to placerville to watch fireworks. Along hwy 50 to left almost to camino, there was cylinder with globes like turnups on each end. like plasma globes, full of electricity. I said to my wife "look at that" she seen and was scared to look. It was hovering like it was interested in us. Drove behind the tress and couldn't see it anymore. I never seen nothing like it.
